Deduction of Japanese Pensions

I have been reporting the full amount of my Japanese pension as Taxable to the IRS
However, it seems that pensions up to 1,140,000 yen are deductible, but I was wondering if anyone knows about this
In other words, should I deduct the 1,140,000 yen from my Japanese pension and then file as Taxable?

One idea is that since the USA covers all income worldwide, you would not deduct the deduction from the Japanese year first
but rather you would account for the full amount and then use the deduction in the USA

. However, I am also of the opinion that since the deduction is taken in Japan, the IRS application should be filed after the deduction

I am waiting for an answer as to which is correct from a legal point of view.
